ELECTRICAL NIGHT-SIGNALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 401,035, dated April 9,1889. Application filed August 7, 1888. Serial No. 282,151, (No model.)

To all whom it may concern;

Be it known that l, EMIL KAsELowsKY, a subject of the King of Prussia,residing at Berlin, in the Kingdom of Prussia, Germany,

have invented new and useful Improvements in Electrical Night-"SignalingApparatus, of which the following is a specification.

\[y invention relates to a system of signaling by night at sea by meansof differently- [0 colored electric lamps which are brought to viewsingly or in groups; and its object is to provide means whereby theelectric current may be switched to and from the signallamps and asupplementary resistance to produce the required signals, and also meanswhereb Y the electric current may be maintained at a constant resistanceand momentary interruption of said current and simultaneousextinguishment of the lamps prevented.

The supplementary resistance employed in connection with thediiterently-colored electric lamps, which are of such number as may benecessary to produce the signals usually required at sea, is preferablyin the form of uncolored electric lamps, which I term compensationlamps, and which ordinarily may be used for illuminating purposes.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in the several views.

Figure l is a sectional elevation of a cylindrical casing containingapparatus embodying my invention. Fig. 2 is a detail view, partlyinsection, hereinafter referred to. Fig. 3 is a diagram of the electriccontacts. Fig. at is a side elevation of the cylindrical casing, andFig. 5 is a diagram of the electric circuits.

In carrying out my invention I employ a cylindrical casing, to,constructed of suitable metal and of any desired and requisitedimensions, and in a bearing, 7L, formed in the center of the top of thecasing, is fitted to turn freely a sleeve, 2', having aligning-In gsformed upon one side thereof, which sleeve contains a spindle, s,capable of vertical and rotary movement therein. In either end of saidspindle are rigidly seated pivot-pins a and b, and in the lugs of thesleeve .2 are also iigidly seated fulcrum-pins c and (.1. A lever, e,

which I term the signal-lever, having a handle,r, and adownwardly-projecting nose, t, is fulcrumed on the pin 0 of the sleeveand pivoted to the spindle on the pin a, the nose of the lever beingadapted to enter notches p in the rim of the casing, as hereinafter morefully explained, the number of said notches corresponding with thenumber of signals to be displayed. A second lever, f,which I term themain contact-lever, is fulcrumed on the pin (Z of the sleeve and pivotedto the spindle on the pin 1).

Upon a plate, it, supported in any suitable manner within or integralwith the casing near its bottom, are concentrically arranged, as shown,in eight groups of four, the contact-springs g, one group havingextensions, forming the contact-springs g, below said plate, as bestshown at lower right hand in Fig. 1. Said group of springs is also shownat the top in Fig. 5. The members of each group of springs areinsulated, in any proper manner, the one from the other.

The contact-lever f, which is knife-shaped, is adapted to be insertedbetween the contactsprings g, as shown in Fig. 2, and the notches p inthe rim of the casing are so situated in relation to said springs thatwhen the nose of the signal-lever e drops therein the lever fsimultaneously enters between said springs. The connections of thecontact-springs with the electric wires are as follows: Of the foursprings in each group one serves to convey the electric current and isconnected with the main circuit-wire m, which is in turn connected withthe positive pole of a dynamo or electric battery, (1, of any approvedform. Of the remaining three springs so many are connected with theelectric wires 21 o q, leading to the signal-lamps s, as the number ofsuch lamps to be displayed in producing the signals may require. Thesprings not thus connected with the signal-lamps are connected to and bysaid wires with the compensation-lamps. Three of the group of springshaving the extensions g, (shown at the lower right hand in Fig. 1, andat the top in Fig. 5,) however, are connected by said wires to thecompensationlamps only. Three signallamps, s, and threecompensation-lamps, Z, are shown in the drawings; but it will beunderstood that I do not limit myself to the use of that number ofeither.

In the present instance, if only two of the three springs for the lampsare employed for the signal, the third spring is connected with one ofthe compensation-lamps Z. If only one signal-lamp is to be used, two ofthe three springs are connected with the correspondingcompensation-lamp; and if the signal and contact-levers be in theposition of rest, as at the point r in Fig. 5, and no signal-lamps arealight, three of the group of springs shown at the top in Fig. 5 of thedrawings are connected with the three compensation-lamps.

Upon a pin seated in a lug bolted or secured in any other proper mannerto the base of the casing is fulcrumed a third lever, y, which I termthe supplementary contact -lever, which is adapted to be kept in contactwith the lower end of the spindle s and between the contact-springs g bya bent spring, 1', se-- cured at one end to the base of the casing andbearing against the under side of said lever. When the contact-lever fis in place between the springs g, the other contact-lever, y, is helddown by the spindle s, in the position shown in full lines in Fig. 1,out of contact with springs g.

In operation, the current being established between the dynamo orbattery and the lamps, and it being desired to display a signal, thesignal-lever e is raised by its handle, thus raising the spindle s andcausing the contactlever f to rise from between the contactsprings g tothe position shown in dotted lines in Fig. 1. The lever e is then turnedto the right or left, as desired, the spindle turning in the sleeve 2,and the nose of said lever is then inserted in the proper notch, p,corresponding with the signal to be displayed. During this rotation thecontact-leverf is held clear of the contact-springs, and but for theintervention of the lever y the electric current would be interruptedand the lamps momentarily extinguished. The instant the spindle israised for rotation, however, the lever y is released and the spring tthen acting carries said lever up between the contactsprings g, thusmaintaining a constant electric current and keeping the lamp alight. Assoon as the signal and contact levers are again depressed, the spindlepresses the lever y down to the position shown in full lines in Fig. 1,out of contact with the springs g. The operation above described isrepeated as often as each change of signal is required.

The compensation-lamps Z may, if desired, be dispensed with, andsubstituted by equivalent resistances of any preferred character and ofequal power. Theymay be dispensed with when a very powerful dynamo orbattery is employed, and in such case the lever y will not be needed,and in such case, also, the number of contact-springs may be increasedor diminished to the number required forsignaling and conveying thecurrent.

If found desirable, instead of conveying the current by connecting oneof the contact ing having a notched rim, a sleeve revoluble,

centrally in the casing, a spindle vertically adjustable and revolublein the sleeve, a lever fulcrumed on the sleeve and pivoted to thespindle, having a nose adapted to the notched rim of the casing, andconcentricallyarranged groups of contact-sprin gs in the casing inelectrical connection with a main circuit-wire, and with opposite groupsof electric lamps in electrical connection with a dynamo or electricbattery, of a contact-lever fulcrumed on and pivoted to the oppositeends, respectively, of the sleeve and spindle and adapted to enter thegroups of contact-springs, substantially as shown and described, wherebyas the spindle is raised, rotated, and lowered the lamps are switchedinto and out of the circuit, and during such rotation the contact-leveris held clear of the contact-springs, as herein set forth.

2. The combination, with a cylindrical casing having a notched rim, asleeve revoluble centrally in the casing, a spindle verticallyadjustable and revoluble in the sleeve, a lever fulcrumed on the sleeveand pivoted to the spindle, having a nose adapted to the notched rim ofthe casing, concentricallyarranged groups of contact-springs in thecasing, one having downwardly-projecting extensions in electricalconnection with a main circuit-wire and with opposite groups of electriclamps in electric connection with a dynamo or electric battery, and acontact-lever fulcrumed on and pivoted to the opposite ends,respectively, of the sleeve and spindle and adapted to enter the groupsof contact-springs, of an auxiliary spring-pressed contact-leverfulcrumed at the base of the casing and adapted to enter the lowerextensions of one of the groups of contact-springs as the contact-levercarried by the sleeve and spindle is raised, substantially as shown anddescribed, whereby, as the lamps are switched into and out of thecircuit and the main contact-lever held clear of the contactsprings, aconstant currentis maintained, as herein set forth.

In testimony whereof I have name to this specification in the twosubscribing witnesses.
